Kathryn Murray is free on bail but has been ordered to stay away from the teen in the case and to avoid contact with anyone younger than 18.

A former Spring Branch ISD teacher accused of having sex with a 15-year-old student in February is expected to be back in court Thursday on three more felonies connected to the alleged relationship.

Kathryn Camille Murray, 29, is accused of driving an eighth-grader from a school dance to a hotel for a rendezvous after two after-school trysts.

The boy told investigators that he and Murray had sex in her Memorial Middle School classroom on Feb. 7 and again two days later.

Murray, an English language support teacher who taught language arts at the school for three years, tutored the Spanish-speaking boy.

The teen told authorities that Murray picked him up at a school dance on Feb. 10 after his father had dropped him off, according to court records, then she took him to a hotel room for two hours, and they had sex.

The next night, Murray is accused of going to the teen's home to have sex with him while his parents were gone. Murray was arrested and charged with sexual assault of a child under 17 years of age after the boy admitted to his mother that the teacher had been at the house.

Three new charges were filed last week after investigators interviewed the teen and looked at surveillance video at the school and the hotel.

When she appeared in state District Judge Michael McSpadden's court in February, Murray agreed to surrender her passport after prosecutors said she was planning a trip to Mexico.

She is free on a $50,000 bail but has to wear a GPS monitor and is barred from contacting the teen or being around anyone younger than 18 years old.
